Title: Improvements in or relating to carburettors for internal-combustion engines using volatile liquid fuel
IPC: F02M3/055
Filed: 1931-01-15
Abstract: 370,988. Spray carburetters. KNOTT, E. W., 54, Ravenscroft Avenue, Golders Green, London, and WYNNE, C. H. L., Guestling Rectory, near Hastings, Sussex. Jan. 15, 1931, No. 1452.. [Class 7 (iii).] Fuel is fed from the float chamber to the nozzle of. a siphon, the siphon action being started by a piston actuated from the throttle valve and acting directly upon the fuel. The carburetter, of the downdraught type, comprises a vertical pipe 10 with choke tube 11 across which extends a nozzle 14 held in place by a grub screw 19. The nozzle, Fig. 3, of streamline form, has an upper boring 15 for fuel, and a lower boring 16 for air admitted by a screw 20, Fig. 1, the two borings being connected by ducts 17, Fig. 3, the aerated fuel being sprayed through downwardly directed ducts 18. A plug 25, Fig. 1, has at its lower end a calibrated orifice 29, boring 27, and annular recess 28, which serve to place the float chamber 21 in communication with a pump barrel 30. This contains a piston 33 loosely mounted on a rod 32 and forced towards the lower end of the rod by a spring 64 bearing against a collar 65 on the rod. The rod and piston are urged towards the top of the cylinder by a spring 34 bearing on a knurled head 35 which carries a spring-loaded washer 42 adapted, when the rod is depressed a certain distance, to close an air inlet aperture 40 which leads to the siphon conduit 39 extending from the bottom of the pump barrel to the nozzle boring 15. The rod 32 is actuated from the throttle 13 through linkage 44, 45. On opening the throttle the piston is depressed and some fuel is forced up conduit 39 to start the siphon action. At the same time air inlet 40 is closed and the siphon action continues. If the throttle be opened suddenly to accelerate, additional fuel is supplied through conduit 39. An additional boring 37 provided with ball valve 38 between the float and pump chambers prevents any lag in the opening of air inlet 40 when the throttle is closed. Fuel from chamber 30 is passed through another siphon to slowrunning apertures 50, 51. In a modification, Fig. 4, the piston is pierced by holes 55 and is adapted to be at the bottom of its stroke when the throttle is closed. It is loosely mounted on a rod 53, an enlarged portion 58 of which serves, in the upper position of the piston to close an air inlet duct 60. The piston is urged towards its upper position by a spring 56, and the turn of the siphon is constituted by apertures 62 in a cap 52 which may be adjusted to vary the height of the siphon and therefore the ratio of fuel to air.

Patent GB-1026272-A (GB)
Title: Dewatering wet paper webs
IPC: D21F3/02
Filed: 1963-01-15
Abstract: Dewatering of a wet web of paper in a papermaking machine is effected by passing the web while in contact with a felt which is itself supported by a substantially incompressible, porous, water-receiving fabric disposed to run in a path inside that of the felt, through the nip of a pair of press rolls, means being provided to remove water in two stages from the porous fabric. Part of the water transferred from the web through the felt to the fabric is further transferred to the surface of the press roll and removed therefrom by a wiper blade (Figs. 1, 4, 10 and 11 not shown).  The second stage of removal of water from the fabric may be effected by passing the fabric around an arc of one or more stationary rods (Figs. 1 to 3 not shown), by directing an air jet through the fabric (Figs. 4-8 not shown) or by drawing air through the fabric and possibly also through the felt by suitably arranged suction or vacuum means (Figs. 9, 10 not shown). Where air is forced through the fabric the moisture-laden air may be passed through a suitable demister and then discharged e.g. through the fabric or recirculated.  In an alternative embodiment (Fig. 11 not shown) the felt and fabric continue after the nip region to travel in contact around part of the press roll, a substantial portion of water being reabsorbed into the felt and being removed therefrom by subsequent passage around a suction roll.  The porous fabric is substantially incompressible and may be of woven metal or plastic material.

Abstract: 452,284. Knitting. ARISTOC, Ltd., and WILLIAMS, H. E., North Street, Langley Mill, Nottinghamshire. Jan. 19, 1935, No. 1839. [Class 74 (ii)] The top of a knitted stocking leg is knitted of about the same slackness as the adjoining welt, and thereafter the stitches are progressively tightened until normal work is being made. A stitch varying and regulating device for the purpose is described as applied to a Cotton's machine. One or more cams 12 are mounted on a shaft 9, and arms 14 carrying rollers 13 co-operate therewith. Each arm is pivoted to an arm 15 keyed to a rocking shaft 7. A cam 17 mounted on a spindle 18, between forks 16, bears on a screw 19 threaded through the arm 14. The cam 17 is turned by a ratchet 20 on the spindle 18. A second ratchet 22 mounted loosely on a sleeve 23 has deeper teeth 34<a> at intervals. As these teeth come round a pawl 27 drops into engagement with the ratchet 20 and feeds it forward. The pawl 27 is carried by an arm moved forward by a spring plunger 29 mounted on a fixed part of the machine. In this way the position of the roller 13 relative to the shaft 9 and hence the position of the needle bar relatively to the sinkers is gradually and progressively varied. Provision is made for resetting both ratchets. Specifications 372,673 and 440,308 are referred to.

Title: Improvements in or relating to automatic liquid measuring and delivering apparatus
IPC: B67D7/16
Filed: 1932-01-21
Abstract: 388,906. Liquid meters. LIQUID MEASUREMENTS, Ltd., and HAMMOND, F., Victoria Road, North Acton, London. Jan. 21, 1932, No. 1874. [Class 69 (i).] In liquid-measuring apparatus of the kind comprising a pair of measuring-vessels adapted to be connected to a common supply and outflow through a throw-over valve automatically operated when one vessel is filled and the other emptied, a clutch interposed between the valve and its driving means is moved into the engaging position by the rise of pressure which occurs when one of the vessels is filled. The throwover valve 23 is splined to a horizontal shaft 13 carrying at one end the axially-movable member 15 of a toothed clutch and connected at the other end to a plate 17 constituting the closureof a collapsable chamber 19 exposed to the pressure of the liquid supply through the port 9. The shaft 13 is axially movable with respect to the casing 7 and the valve 23. A shaft 31 coaxial with the shaft 13 carries the other member 35 of the clutch and is driven from the pump by chain gearing 37. When one measuring chamber is filled the rise of pressure in the supply chamber 29 causes the bellows to collapse and the clutch parts to be engaged to reverse the valve. To ensure engagement of the clutch parts, cams 55 on the plate 17 engage spring plungers 57 projecting into the chamber 29. To prevent the clutch parts being engaged until the discharging chamber has completely emptied a lever 41 extends into the path of the shaft 13 and carries pivotally at its free end a bell-crank lever 45 one arm of which is connected by a link 47 to a float 49 in the discharge chamber 27 so that when the float falls to its lowest position the other arm of the bell-crank is moved into the path of a second lever 43. The lever 43 is engaged by a cam 51 on the shaft 31 so that it continually rises and falls while the pump is working, and when the float is at its lowest position the lever 41 will be moved out of the path of the shaft 13.

Title: Improvements relating to electric selective distant control systems
IPC: H02J13/00
Filed: 1928-01-20
Abstract: 283,966. Maurer, G. Jan. 21, 1927, [Convention date]. Selective distant control systems; tell-tale apparatus. - In a system for selectively controlling a number of circuits C, D, E, any one of the circuits may be opened or closed by transmitting a characteristic impulse code which operates a master member at the receiver to close the circuit of an electric motor and thereby drive a follow-up device and a selector switch. In the arrangement shown, three pairs of electromagnets 10, 11 are selectively operated by a manuallyoperated transmitter B to open or close the load circuits C, D. E. When the handle 70 of the transmitter B is rotated into a predetermined position to effect a selection, a contact arm passes over contacts 63 to transmit a characteristic number of impulses. over the line 67 and operate an electromagnet 43 which controls ratchet wheels 39, 50. The ratchet wheel 39 carries brushes 44, 45 which normally are positioned opposite recesses in the conducting drums 25, 26 but when stepped forward make contact with the drums 25, 26 to close the circuit of the motor 12. The motor rotates a drum 13 having spaced contacts co-operating with brushes 23 connected to the electromagnets 10, 11 and simultaneously rotates the drums 25, 26 to open the motor circuit and thereby position the drum 13 to select the appropriate magnet 10, 11. The ratchet wheel 50 carries brushes 52 which normally engage projections on conducting drums 27, 28 on the motor shaft and is stepped forward simultaneously with the ratchet wheel 39 to open the control circuit of the relays 10, 11 but when the follow-up drums 25, 26 return to their normal positions relative to the brushes 44, 45, the control circuit of the selected magnet is closed over a circuit from battery 35, lead 57, selected magnet 10 or 11, brush 23 and associated contact on the drum 13, contact 18, brush 22, drums 27, 28, brushes 52 and leads 55, 56 to battery. The selected magnet operates a contact 9 to open or close the associated circuit C, D or E. The handle 70 is held in its selecting position by a spring detent which engages notches 69 in the front plate of the transmitter and simultaneously raises an indicator behind an aperture. The indicators associated with any one circuit to be controlled are mounted on the ends of a pivotally mounted bell-crank lever 74 which also carries contacts 80, 81 for controlling electromagnets 84, 85 adapted to move an indicator behind one or other of the apertures 87, 88. A step-by-step indicator F is connected in the line circuit and is operated by the transmitted impulses.
